Welcome to Evc Bandie. Some people here are pretty smart (others of us are good at pretending).
Regarding your post:
Did it not occur to you that physicists and cosmologists who know a LOT about thermodynamics, the big bang (and general relativity which underlies it) and general physics would know about all the things you've mentioned?
Do you actually think that they aren't aware of these issues? Do you think that if they were real problems for the idea of the big bang that it would still be considered a viable theory?
Others will probably discuss them with you.
